Tomcat启动报错：Name or service not known

今天把项目发布到线上Tomcat服务器的时候 使用./start.sh 启动以后，在logs目录中使用tail -f catalina.out的时候
发现报错如下：

Unable to set localhost. This prevents creation of a GUID. Cause was: ecs-b5aa-0001.novalocal: ecs-b5aa-0001.novalocal: Name or service not known
java.net.UnknownHostException: ecs-b5aa-0001.novalocal: ecs-b5aa-0001.novalocal: Name or service not known
    at java.net.InetAddress.getLocalHost(InetAddress.java:1505)

按照经验应该是这个名字ecs-b5aa-0001.novalocal的问题

解决方案：

修改/etc/hosts文件，添加相应配置，问题解决 
如下： 
127.0.0.1 ecs-b5aa-0001.novalocal
